My friend has a moto phone, and for some reason, when ever he updates the phone, the notification ringer resets back to default. I've sent in an ask already, but the constant hearing of that phone going off is making me wanna snap it. The same also happens with do not disturb, the phone just turns it back off afterwards. Is there anything we can do? He got the phone last year, neither of us understands why it does this. Do we need to call the manufacturer?
